Purple Crystal Tiles: Monster Spawner. This tile spawns monsters twice as fast as normal monster spawning. So every time a monster spawns on a normal tile in a dungeon, these tiles spawn 2.

Iron Fences: Gates. They require something to open them. For instance: some require you to disable all spawners in a room or kill a certain amount of monsters. The Boss Room gate requires you to get all four keys in a dungeon and unlock it.

Blue Tiles on wall: Teleporters. Most teleporters you see will be one-way. Meaning that monsters can teleport into the room but you can't teleport into the monster spawn room.

Green Spikes: Spikes. (In the game they won't be green, since the texture was grey Minecraft turned it green.) These spikes kill you instantly, so don't fall into them.

Tiles on the wall that look like they have a hole in them: Launchers. These launchers can either shoot air to push you or a projectile to hurt you. Most of these are seen in Boss Rooms or in Spike Danger Rooms.

I started development on Dexesta today. I've been doing some textures for dungeons and foliage. Later I'll post some screenshots of an example dungeon later. I don't have any experience coding, but my friend is learning Java and eventually I will also. You may also be wondering how I will post screenshots when I don't have a Game Engine yet. I am designing example maps with Minecraft (Made by Mojang) and then applying the textures since the landscape tiles textures are 16x16 and therefore compatible with Minecraft.

So yes, I am short of code which mean I will be needing coders. Currently I am not accepting helpers, but I might later. Of course you would work for free, since this game is free. You would have deadlines depending on your project and if you don't finish your project on time I will not accept your work.
